OEM Carrier Hot Surface Spark Electrode Igniter 48VL400002 for Model PY4GNAB60115AA

This OEM spark electrode igniter (Part# 48VL400002) is the factory-specified replacement for the Carrier PY4GNAB60115AA packaged gas/electric unit. The hot surface igniter is the first component in every heating cycle — it heats to ignition temperature to light the gas burner. When it cracks, burns out, or fails to reach proper temperature, the control board cannot confirm ignition and the system enters hard lockout, leaving you with no heat and a blinking fault code. Replacing this OEM igniter restores reliable ignition and eliminates nuisance no-heat service calls.

• Specs: Spark electrode / hot surface igniter | Factory OEM part for Carrier PY4GNAB60115AA | 120V ignition circuit compatible | Direct drop-in replacement — no modifications required
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory geometry, element composition, and temperature rise specs. Generic igniters often have mismatched standoff dimensions or inferior silicon carbide formulations that crack prematurely under thermal cycling, leading to repeat failures within one season.
• Install difficulty: 2/5 — Turn off gas supply and 120V power before starting. Tools needed: 1/4" nut driver, flat-blade screwdriver, needle-nose pliers. Avoid touching the igniter element with bare hands — skin oils cause hot spots that shorten service life. Photograph all wire connections before removal.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
